Vertebral hemangioma
Vertebral Hemangioma
Vertebral hemangioma (pronunciation: ver-te-bral he-man-gee-oma) is a benign tumor that develops in the vertebrae, the series of small bones that make up the spinal column.
Etymology
The term 'vertebral hemangioma' is derived from three words: 'vertebral', referring to the vertebrae; 'hema', a Greek root meaning blood; and 'angioma', a term for a tumor that arises from blood vessels or lymph vessels.
Definition
Vertebral hemangiomas are benign vascular lesions of the spine that are often discovered incidentally on imaging studies. They are the most common benign spine tumors, with a prevalence of 10-12% in the general population.
Symptoms
Most vertebral hemangiomas are asymptomatic and do not require treatment. However, in rare cases, they can cause symptoms such as back pain, neurological deficits due to spinal cord compression, or pathological fracture.
Diagnosis
Diagnosis of vertebral hemangioma is typically made through imaging studies such as MRI or CT scan. The characteristic appearance of a vertebral hemangioma on imaging is a vertically oriented, honeycomb or grid-like pattern within the vertebral body.
Treatment
Treatment for symptomatic vertebral hemangiomas may include radiotherapy, embolization, surgery, or a combination of these modalities. The choice of treatment depends on the patient's symptoms, the location and size of the hemangioma, and the patient's overall health.
